This emissivity table is only used to provide a reference ratio for the emissivity of different commonly used materials. The actual emissivity. For some substances, the emissivity will change with the temperature and wavelength, especially for metals. It may vary greatly due to the surface finish, oxidation degree, and surface contaminants. Emissivity of the measured object Emissivity of the measured object Asphalt. Asphalt concrete This emissivity table is only used as a measure of the emissivity of different commonly used materials. Reference comparison to actual emissivity For some substances, the emissivity will change with temperature and wavelength. Especially for metals, it may be greatly affected by the surface finish, oxidation degree, and surface contaminants. The change of measured object emissivity measured object emissivity asphalt.
